Defensive Driving Part VII: Drug & Alcohol Supervisor and Driver Training

The Department of Transportation (DOT) requires supervisors of Commercial Driver’s License (CDL) drivers to complete 60 minutes of training on alcohol misuse and 60 minutes on controlled substance use to recognize reasonable suspicion of impairment. The objective of the training is to equip supervisors with the information and resources to identify physical, behavioral, speech, and performance indicators of substance abuse in drivers and guide them through the proper referral for testing. Additionally, drivers can undergo separate training to understand their rights, responsibilities, and the consequences of a positive test.

Why is Training So Critical?

According to data from the Federal Motor Carrier Safety Administration (FMCSA), about five percent of trucking accidents are caused by commercial drivers under the influence of drugs or alcohol. The prevalence of alcohol and other drug use among truck drivers can impair their cognitive functioning and behaviors, which can impact how they drive, causing them to drive faster or make poor decisions about road conditions, for instance. Under the FMCSA regulations, a commercial truck driver is considered intoxicated if their blood alcohol concentration (BAC) is 0.04 percent or higher.

What Topics are Covered for Supervisors?

Topics include identifying the physical signs of alcohol or drug use (such as coordination issues, changes in appearance, or odor), behavioral indicators like mood swings or erratic actions, and speech or performance changes that may signal impairment. Supervisors also learn how substance use can impact safety, productivity, and team dynamics, as well as the proper steps to take when making a reasonable suspicion determination, including confidentiality protocols, documentation requirements, and best practices for employee communication.

Several online and in-person courses are available from third-party providers to meet the DOT requirements.

Note: This training requirement does not apply to owner-operators who are the only driver in their company.

How About Training for Truck Drivers?

Although formal drug and alcohol training isn’t required for drivers, it plays an important role in keeping both drivers and the public safe. Training helps drivers understand not only the legal requirements around testing and prohibited substances but also the real-world consequences of impairment, from slower reaction times to judgment errors that can cause serious accidents.

Driver-focused training typically covers topics such as the effects of alcohol and controlled substances on performance, warning signs of dependency or misuse, and the importance of self-reporting and seeking help early. It also reviews FMCSA regulations, testing procedures (including pre-employment, random, post-accident, and reasonable suspicion testing), and what to expect during the testing process.

Truckers who fail a drug or alcohol test are immediately removed from all safety-sensitive duties, such as driving a commercial motor vehicle, and are required to complete a federally mandated “return-to-duty” process. This includes assessment and treatment by a qualified substance abuse professional (SAP), followed by mandatory follow-up testing.

Are You in Compliance with Mandatory DOT Supervisor Training for CDL Drivers?

Supervisors overseeing CDL drivers must undergo mandatory training to recognize signs of drug and alcohol misuse and comply with FMCSA and USDOT regulations. Training ensures your team maintains road safety and fulfills federal requirements.

Supervisor Training Requirements

Employers must ensure that all personnel assigned to supervise drivers (CDL) obtain at least 60 minutes of alcohol misuse training and an extra 60 minutes of controlled substance use training. Supervisors will use the training to assess whether there is reasonable suspicion to ask the driver to undergo testing under 49 CFR § 382.307. The training must contain physical, behavioral, speech, and performance signs of potential alcohol abuse and controlled substance use. Recurrent training for supervisory workers is not necessary.

Although owner-operators are not required to take this training, you still must be registered with a consortium for DOT drug and alcohol testing.

Where Training Is Available

The FMCSA has supervisor training available in video format that can be downloaded from their website for free:

Ensure Compliance, Safety on the Road

In addition to meeting federal requirements, this mandatory supervisor training promotes a safer working environment. Supervisors can take immediate action if they suspect a driver is under the influence of drugs or alcohol, which helps prevent impaired drivers from continuing to operate commercial vehicles and reduces the risk of accidents. In addition, knowing that they can be tested based on reasonable suspicion serves as a deterrent for drivers who might otherwise consider using drugs or alcohol. The possibility of being tested encourages drivers to adhere to safe and sober driving practices.
